A SAKICHI NAKAHARLA, OF. SEATTLE, WASHINGTON.

DAUBER BRUSH.

Application led March 17, 1923. Serial No. 625,856.

To all whomy it may concern:

Be it known that I, AsAKroHr NAKAHARA, a subject of the Emperor of Japan, residing at Seattle,'in the county of King and State of Washington, have invented a new and useful Dauber Brush, of which the following is a specification.

y invention relates to improvements in dauber brushes and the principal objects of my invention are to provide a dauber brush with a handle serving as a reservoir in which the semifluid substance is carried in a collapsible tube with means for 'causing said substance to be forced outwardly to the bristles of the brush for constant and convenient use and means for controlling the passage and supply of said substance at all times. For the purpose of illustration, l have confined myself to a shoe brush but it will be understood that the device is equally adaptable to all brushes used for the application of duide and semiiiuids.

With the above and dther objects in view which will appear as the description proceeds, the invention consists of thel novel construction, adaptation, arrangement and combination of parts hereinafter described and claimed. f

These objects are accomplished by devices illustrated in the accompanying drawings, 'Wherein- Figure 1 is a view in side elevation of a dauber brush embodying the exterior features of the invention;

Fig. 2 is a view-in horizontal section taken substantially on a broken line 2, 2 of Fig. 1;

Fig. 3 is a view in longitudinal vertical p section taken substantially on a broken line 3, 3 of Fig. 2;

Fig. 4 is a view in transverse vertical section taken substantially on a broken line 4, 4 of Fig. 3; and

Fig. 5 is a view in transverse vertical secclon taken on a broken line 5, 5 of Fig. 1.

' Referring to the drawings throughout which like reference numerals .are used to designate like parts, the numeral 5 designates the head of a dauber shoe brush having an annular shoulder 6 on its side. Extending in a direction normal to the axis of said head and the brush proper is a trough 7 which is substantially semi-circular in crosssection and is rigidly secured at its inner end to said annular shoulder. A cylindrical handle 8 is arranged to fit snugly over said trough and is securely held on said ana L-shaped slot 10.

nular shoulder by a pin 9 working in an A longitudinal slot 11 extends the greater length of said handle diametrically opposite said trough and a clip 12 is provided near the outer end of said trough for reasons more fully described hereinafter.

A bypass 13 threaded on its outer end extends concentrically through the annular shoulder 6 and into the head 5 where it communicates with an opening 14 extending vertically through said head.

The lower end of the head 5 is provided with a dauber brush- 15 which is threadedly secured to said head and an opening 16 extends centrally through same'and registers with the opening 14. A spreader brush 17 is adapted t fit on the upper end of said head by means of an annular shoulder 18 and a corresponding socket.

A depending valve stem 19 is concentrically formed on the shoulder 18 and is adapted to lit snugly within-the openings 14 and 16' as clearly shown in Figs. 2, 3 and 4 of the drawings. Said valve stem extends through said openings and partly through the bristles of the brush 15. A groove 20 is provided in said stem normally extending from above' the bypass 13 throughout its entire length.

1n using the device the handle 8 is removed and a collapsible tube 21 is placed in the trough 7 with its neck 22 screwed into the bypass 13 and its opposite end bent under the clip 12 to pre-vent same from slipping. A ball 23 is then pressed into lace against the closed end of said tube and the handle 8 is installed and secured in place b v means of the pin 9 and slot 10. The ball 23 projects slightly within the longitudinal groove 11 and. it will be obvious that the device is now ready for use. i'lhe brush 17 is turned until the groove 20 of the valve stem 19 registers -with the bypass 13. Bv pressing the ball 23 forward with,

the thumb along the groove 11 the contents of the tube 21 will be forced outwardly through the bypass 13 and downwardly through the groove 20 to the bristles of the brush 15,

The paste is then applied to the shoe or other object by the brush 15 in the usual manner and may be spread over the entire shoe by the brush 17. lt will be obvious that the supply of paste may be regulated by turning the brush 17 carrying the valve 19 and may be entirely cut. oil by turning said valve far enough to close the bypass 13.

While I have limited the description and drawings to a dauber brush for the application of shoe polish, it Will be apparent that of operation of my dauber brush Will be readily apparent to those skilled in the art to which the invention relate-s, and it will be understood that the apparatus shown is merely illustrative and that such changes may be resorted vto as are Within the scope and spirit of the invention.

Having thus described my invention What I claim and desire to secure by Letters Patent is A brush of the character described comprising ahead having a vertical opening therethrough, an annular shoulderl on said head having a bypass therein vcommunicaty ing with said vertical opening, a semi-cylindrical trough secured to'said shoulder, a

collapsible tube having its neck threadedly secured in said bypass and its opposite end secured by a clip adjacent the outer'end of.

said trough, a hollow cylindrical handle adapted to fit over said trough and tube having a longitudinal slottherein, means collapsible tube through said longitudinalv slot to force its contents through said head to said dauber bristles.
